Key result
Preoperative risk factors and surgical complexity combined predicted 49% of hospital cost variation (P<0.001), whereas postoperative complications predicted only 20%.

Do preoperative risk factors and surgical complexity predict hospital costs better than postoperative complications in surgical patients?
Population
5875 patients on 6 surgical services from a single center
Comparison

Preoperative factors may drive costs more than complications; supports risk-stratification research but leaves causal interventions open.

Do preoperative risk factors and surgical complexity predict hospital costs better than postoperative complications in surgical patients?
p-value: p=<0.001
Preoperative risk factors and surgical complexity are stronger predictors of hospital costs than postoperative complications, suggesting preoperative risk reduction could yield significant cost savings.
Davenport et al. (2005) conducted an observational in Surgical patients (n=5,875). Preoperative risk factors and surgical complexity vs. Postoperative complications was evaluated on Hospital cost variation (p=<0.001). Preoperative risk factors and surgical complexity combined predicted 49% of hospital cost variation (P<0.001), whereas postoperative complications predicted only 20%.
